🧪 Add tests for GetServiceRegistry and GetFamilyNames

[adcondev]

🎯 What: Missing tests for GetServiceRegistry and GetFamilyNames functions in internal/service/registry.go have been implemented to ensure accurate construction of service variants.

📊 Coverage: The new tests cover:

• Correct mapping output of keys to variant lists in GetServiceRegistry
• Correct matching of service family types (Local and Remoto variants)
• Output formatting and validation for all struct fields on each Variant utilizing validateServiceVariantFields.
• Completeness and correctness of GetFamilyNames

✨ Result: A significant improvement in coverage that acts as a strong guardrail for the registry and the integrity of system variants mappings.
